Draw and annotate a stress strain curve of a polymer

Characteristics of polymers:

1. High corrosion resistance

2.Lower density

3.Cost of production is low

4.Specific strength is high.It means that weight to strength ratio is high that is why polymer light in weight.

5.Polymer can be handle easily

6.Polymers have resistance to thermal and electric conductance.

The categories of polymers

1. Elastomers

2. Brittle plastics

3.Plastics

The strain stress curve for different polymers.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
